A COMPLETE AGENT WORKSPACE
From idea to working agent team
Build your agent system with visual tools, then keep full control of every file and every action.
Chat with your workspace
Mention any artifact with @. BlackAgents loads its
context, linked rules, skills, and memory into the conversation.
Agent workflows
Line up agents like a production team. Pass work from one step to the next and review every result.
Tools with guardrails
Read files and call MCP tools. File writes and commands pause until you approve them.
Relationship graph
See how agents, commands, rules, and skills reference each other across the workspace.
Second brain
Turn feedback into proposed memory, skills, and rules. Nothing changes before your review.
ONE MODEL, FOUR BUILDING BLOCKS
A clear place for every kind of context
Commands wire. Agents execute. Rules constrain. Skills educate.
